Charlie thinks that a six comes up less often than the other numbers on the dice. Have a look at the results of the test his class did to see if he was right.
Use the two sets of data to find out how many children there are in Classes 5, 6 and 7.
It's easy to work out the areas of most squares that we meet, but what if they were tilted?
Here are four tiles. They can be arranged in a 2 by 2 square so that this large square has a green edge. If the tiles are moved around, we can make a 2 by 2 square with a blue edge... Now try. . . .
Charlie and Alison have been drawing patterns on coordinate grids. Can you picture where the patterns lead?
Choose a couple of the sequences. Try to picture how to make the next, and the next, and the next... Can you describe your reasoning?
A number of contributions shed light on this problem.
Go to last month's problems to see more solutions.
Written for teachers, this article discusses mathematical representations and takes, in the second part of the article, examples of reception children's own representations.
The aim of the game is to slide the green square from the top right hand corner to the bottom left hand corner in the least number of moves.
